Benj. H. Bradley, of Cheshire, Conn., has invented an improvement on friction sash fasteners, for which he has taken measures to se- i core a patent. Mr. B. employs a sliding plun- I ger, with a friction roller in the head sur- J rounded by a spiral spring and placed within a barrel, the whole being inserted in the sash of the window, the rollers (one being used upon each side) press against the frame and secure the window by friction at any desired j position: this arrangement shows no appearance of a fastener on either side oi the window, and is a very cheap fixture. Some French Savans have called a meeting of philologists, to be held in Paris next , month, to devise means for adopting a uni- ilj versal language.
